-DRAIN '11min Application led. April' 8,

This invention relates to plumbing fixtures and more particularly to drain traps' for sinks and the general object thereof is to provide an attachment adaptable to standard trap fittingswhich will permit of a convenient and sanitary manner for draining foul, extraneous matteil from the trap. v A further object 'of vmy invention is rto provide a device including' a trap' plug, which device may be attached to a goose neck trap fitting insuch manner that the plug may be shifted from vthe trap opening withouty experiencing the usual annoyance of contact with foul matter escapingv from the trap. i

Other objects of my invention `will herein-l after become apparent from .the following description which refers to the accompanying drawings illustrating a preferred embodiment thereof. The essential characteristics are summarized in the claims.

In the drawings, Fig. 1 is a side elevational view of a goosey neck trap fitting equipped with my novel plug-holding attachment; Fig. 2 is a plan view of the fitting of the device shown in Fig. 1; and Fig. 3 is a cross-sectional view taken substantially along line 3-3 of Fig. 2.

My invention contemplates the provision of a device having a plug which lmay be readily attached to a standard goose neck trap fitting to thereby replace the usual threaded plug. The character ofthisf device is such that the plug may be dropped away a. substantial distance from the goose neck fitting to permit the trap to be emptied of undesirable matter and which may' be operable tov place the plug in water-tight connection over the trap opening. In Fig. l of the .drawings I show a goose neck trap 10 of the usual standard design having a lower short apertured branch 11 provided with an opening 12 for emptying the trap when desired. I seal this opening with a plug 14 of a convenient form tofcarry a resilient gasket or washer 15. Y

In order that the plug may be dropped away from the fitting 10 without necessitating the soiling of the hands of the manipulator, I pivotally suspend the plug upon a pair of vertically extending members 16 which are attached at the upper endsthereof to lever members in the form of bell cranks 17 which may be pivotally mounted 1926. semi No.l 100,521'.,V

upon an attachable collarv18as shown at 17a. of a'convenient form to permit ready attachment of the devicepto Yone leg ofthe standard fitting 10.Y The collar .18 may be provided with perforated ears 19 to receive a pin or screw 20 and these ears are formed to be` spacedgapart a sufficient distance to permit the mountingof a cam lever 22 therebetween. A

`The upper end of the lever 22 isformed to afford attachment for two link members 27 which are pivotally attached to the front legs of the bell crank levers 17 as shown at 27aand this lever member is also provided with a cam or locking portion 23 which may engage thejwall ofthe fitting leg to which the collar 18 is attached. When the lever is in the position shown in Fig. 1, the cam portion is vwedged against the fitting, thus securing the members 1o and bell crank lever 17 in the position shown and in this upward position, the plug 14 is urged upwardly :with sufhcient force to cause compression of the gasket 15 on the branch 11 of the fitting, thus sealing the opening 12 of the fitting.

If desired, a guide means may be provided for spacing and guiding the members 16 and such means may comprise a flat member 24 secured to the fitting in any suitable manner such as a screw 25 at a point in alignment with the branch portion 11 of the fitting.

To drain the trap'the cam lever is shifted to the position shown in dotted lines in Fig. 1, thus causing the'plug to be lowered away from the Vfitting. and to close the fitting the cam lever is shifted to the full line position. In this 'latter position the pivotal connection between the respective members comprising the attachment'are shifted past normal dead center positions thus causing the plug to be locked in sealed relation to the fitting opening.

From the foregoing description of my invention, it will be seen that I provide asimple device for suspending a drain trap vplug when itl is desired 'to open the trap and for maintaining the' plug in seal-ed relation to the trap when the trap is in use and that this device is of such form as to be economically manufactured and readily attached to a trap of standard dimensions. Furthermore, it will be lnoted that the operating means for the plugis disposed above rao the trap opening whereby the plug may be dropped away from the fitting Without any resulting discomiture to the manipulator of the device.

I claim: Y

l. In a device oi' the character describe7 the combination oi' a drain fitting, there being a drain opening formed in the low-er part oi the fitting, a plug for sealing-the opening, said plug' having a resilient mem-l ber 'mounted thereon to engage the iitting around sai-d opening, a pair of upright members attached to the plug for pivotally suspending the plug, laterally eXt-endingguidf ing means for keeping said upright members in alignment with the opening of the titting when the plug is dropped therefrom and lever members including al cam lever for locking said upright members in such posiffl `tion as to cause said plug to seal the opening.

2. In a device oi the character described,

the combination of a. drain fitting having a lfirst named members to bring the gasket on .the combination cfa plug i'or sealing said opening and a pair of arms extending upwardly and adapted to carry said plug, a member secured to the U opposite the openying for-guidingsaid arms, a band shaped member engaging one leg of the U `above the opening, a pair-oilbell cranks pivot-ally mounted on said last named member engaging the upper endsof said armsito suspend the -arms in a substantially vertical positron,

`a selflocking handle carried by said4 band *trom the bend of the U ier holding the piugin sealed relation to the drain opening of the tting, said self locking means being' attachably secured to one leg' of the trap .by a contractable band member embracing said U leg. Y

In testimony whereof, I hereunto afiiX my signature. l
